| Solubility | It is recommended to reconstitute the lyophilized Interleukin 7 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized Interleukin-7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IL7 should be stored at 4°C between 2-7 days and for future use below -18°C .For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Biological Activity | The ED50was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is less than 0.2 ng/ml, corresponding to a specific activity of >5.0б┴106 IU/mg. | ||
| Formulation | Filtered (0.2µm) and lyophilized from a concentrated (1mg/ml) solution in 1б┴PBS, pH7.4 and 2% trehalose. | ||
Interleukin-7 is a potent lymphoid cell growth factor produced primarily by stromal cells. IL-7 has been shown to support the proliferation and differentiation of pre B- and early T cells as well as displaying a biological effect on cells of NK and myeloid lineages.
The ED50was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is less than 0.2 ng/ml, corresponding to a specific activity of >5.0б┴106 IU/mg.
